The ST-114 is a flexible PC/AT ISA bus evaluation platform for the Intersil HSP50214 Programmable Downconverter. Within a matter of minutes after installation in a PC, the ST-114 is up and running. The board simultaneously generates and tunes signals anywhere from dc to 20 MHz. Signal types include FM, FSK, BPSK and QPSK. Tuning and demodulation are completely digital and allow nearly continuous bandwidth and data rate selection up to 1.2 MHz.
